FAR and DFARS › FAR Part 4: Administrative and Information Matters › Subpart 4.21

FAR 4.2102 Prohibition.

The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.

In plain English

This section prohibits agencies from procuring or obtaining equipment, systems, or services that use covered telecommunications equipment or services as a substantial or essential component or critical technology, and from contracting with entities that use such equipment or services. The prohibitions took effect August 13, 2019 for procurements and August 13, 2020 for contracts with entities using covered equipment, unless an exception or waiver applies. It matters to contractors because their use of covered telecommunications equipment or services can affect their eligibility for Federal contracts, even if that use is unrelated to the contract work.

Applies to: Agencies and contractors providing or using equipment, systems, or services
